Referring to the drawings, A is the radiating element consisting, in the installation shown, of a continuous coil of radiating pipes, B the train pipe, C, C the supply pipe of the radiating coil, D a discharge pipe leading from the radiator, E a'controlling deviceor' vapor regulator which is interposed between the-two sections 0, C of the supply pipe and to which the discharge pipe D leads, and F a four-wayshut-ofl' valve the purpose of which is to either direct the steam from the supply pipe into the radiating element and from the radiating element to the discharge pipe, or to short circuit the steam from the supply pipe directly to the discharge pipe and cutting out the radiating coil and placing the 1nlet and outlet ends A, A thereof incommunication with each other. The vapor regulator E is of familiar construction'and operates bv means of a valve interposed between sections C, C of the supply pipe and a thermostat under influence of the medium discharged through discharge pipe D 1 to maintain the steam in the radiator A, when the latter is in service, 'ats'ubstantially atmospheric pressure. I When the four-way valve F is manipulated to cut out the radiator the steam is short circuited to the thermostat of the controlling device E in just suflicient quantities to keep the controlling device from freezing up as is well known in systems of this type: a

' The four-way valve F is constructed as follows: 10 is a casing provided with interior web's 11,12, 13 and 14, dividing the easing into a chamber 15 communicating with a supply pipe, a chamber 16 with which the inlet end A of the radiator is connected. a chamber 17 to which the outlet end A of the radiator leads, and a chamber 18 communicating with the discharge pipe D. 19 is a valve -body arranged in the space beinterior webs and formed at the top with a disk 20 and at the bottom with a disk 21. The valve body is provided with a stem 22 extending through a bonnet 23 on the top of casing 10 and provided with a handle 24:, a spring 25 being preferably interposed between the bonnet and the upper disk 20. A drainage pipe 26 is tapped into the under side of the valve casing beneath the lower disk 21 of the valve body and the bottom of the casing is formedwith port-27with which a port 28' in the disk 21 registers when the valvebody is in its short circuiting positiQILU The drainage port 27, 28 is designedto permit the outflow of water of condensation, from, y,

the radiating-coil "when steam is shat off from the latter, that is when thevalvebody;

of this H character. To rovercome this the valve'body is formed with a verticaLport 29 communicating with the radiatorside1ofthe valve -by'a shortbranch port 30 and with the drainage-pipe ,26 by arcuatebranch port 31' in thelower disk 21,thelatter-being adaptedto register with a port-32 in the bottom; ofthevalve casing. when the valve body isituaned to its short circuitirg position. Thus an ;air\, inlet ductis provided which opens intotheradiatorside of the valve preferably atthe topcthercoil This preventstthe,formation of-a vacuum in the radiator pipes so that the water of-condensation which accumulates therein may; outflow freely; through; the discharge port :27, 28.
